I'm confused on the mag timing for an O-200A engine. AD 96-12-06 restricts timing to 24º btc unless all four cylinders meet a part number requirement, in which case it allows timing to be set at 28º btc. However TCDS E-252 rev 34 calls for 24º btc only. What should the timing be for an engine if all four cylinders meet the 28º requirement?
